Each burn is reduced to 10 or 20 ms to achieve this. The authors report their early experience with this system. METHODS 75 procedures done in 60 patients divided into four groups-group A, patients undergoing panretinal photocoagulation (PRP); group B, patients undergoing focal or modified grid macular laser; group C, patients undergoing macular grid and group D, patients undergoing retinopexy-were retrospectively studied.

Significantly higher powers were required with the Pascal than with conventional laser (p
